Understanding "BIMI record"

BIMI (Brand Indicators for Message Identification) is a recent standard that displays your official brand logo directly next to your emails in compatible mail clients (Gmail, Yahoo, some mobile clients). Unlike the other DNS checks in this category, BIMI isn't a security mechanism in the strict sense — it's a visual trust bonus reserved for domains that already have flawless email authentication.

BIMI has a strict requirement: it only works if DMARC is already configured with an enforcement policy (quarantine or reject, not none). It's a reward for the maturity of your email setup, not a starting point.

How TheSiteFuse checks "BIMI record"

TheSiteFuse queries the TXT record default._bimi.<domain> and looks for a value starting with v=BIMI1. If present, the check passes and displays the configured logo URL. If absent, the result is marked "na" (not applicable) rather than a failure — BIMI remains an optional enhancement, never a baseline security requirement.

Why "BIMI record" matters

  • Not a security risk — the absence of BIMI doesn't make your domain vulnerable; it simply denies your emails an extra visual trust signal for recipients.
  • Missed marketing opportunity — for a brand with a strong visual identity, automatically displaying the logo in the inbox improves recognition and can slightly boost open rates.
  • Indirect maturity signal — BIMI's presence implicitly tells recipients (and spam filters) that the domain has a strict, well-established DMARC configuration, strengthening overall trust in your emails.

Fix "BIMI record" step by step

Mandatory prerequisite

First verify your DMARC record is in p=quarantine or p=reject policy (see the dedicated check) — BIMI will be ignored by mail providers without it.

Prepare the logo

The logo must be in SVG Tiny PS format (a restricted subset of SVG), square, with a solid-colour background. Online conversion tools exist to transform a standard SVG into this specific format.

Publish the DNS record

Name: default._bimi.yourdomain.com
Type: TXT
Value: v=BIMI1; l=https://yourdomain.com/logo-bimi.svg;

VMC certification (optional but recommended)

For the logo to display in Gmail, a Verified Mark Certificate (VMC) — a paid certification proving ownership of the registered trademark — is generally required in addition to the DNS record. Yahoo and some other clients display the logo without a VMC.
